Installation, Operating & Service Manual
A . GENERAL GUIDELINES
1. Direct Vent system must be installed in accordance
with these instructions and applicable provisions
of local building codes. Contact your local fire
and building officials on specific requirements
for restrictions and the installation of fuel oil
burning equipment. In addition, for boiler
installation in United States, consult with a
professional knowledgeable on requirements
of NFPA 31-
Standard for the Installation of Oil-
Burning Equipment
and NFPA 211
Standard
for Chimney, Fireplaces, Vents and Solid Fuel-
Burning Appliances,
latest editions.
2. In the Direct Vent configuration, all air for
combustion is supplied directly to the burner
from outdoors, and, flue gases are vented directly
outdoors (thru wall), via Direct Vent System
(FDVS), which is a non-positive pressure vent
system termination for oil-fired appliances, that
provides an outlet for products of combustion,
and, an intake for combustion air in a single
concentric terminal.
3. Direct Vent Hood Assembly minimum clearance
to combustible material is 0".
4. Maximum wall thickness that FDVS vent
termination may be installed through is 12".

WARNING
This venting system must be installed by a
qualified installer (an individual who has been
properly trained) or a licensed installer.
DO NOT locate vent termination where exposed
to prevailing wind. Moisture and ice may form
on surfaces around vent termination. To prevent
deterioration, surface must be in good repair
(sealed, painted etc.).
DO NOT locate vent termination where
petroleum distillates, CFC's, detergents, volatile
vapors or any other chemicals are present.
Severe boiler corrosion and failure will result.
DO NOT locate vent termination under a deck.
5. Locate the vent terminal so vent pipe is short
and direct, and, at the place on exterior wall
that complies with the minimum distances as
specified in Figure 16 and listed as follows. The
vent termination must be located (as measured
to the bottom of vent terminal):
a. Not less than 12" above finished grade or
expected snow accumulation line whichever
is greater.
b. Not less than 3 ft above any forced air inlet
located within 10 ft.
c. Not less than 4 ft from any door, window or
gravity air inlet.
